Serratin a new metabolite obtained from Serratia marcescens, a bacterium isolated from the microflora associated with banana plantations

摘要

When cultures of Serratia marcescens, an enterobacteria isolated from the microflora associated with banana plantations incubated at 27°C in a yeast-calcium carbonate-dextrose solid medium (10 g of yeast extract, 20 g dextrose, 15 g bacteriological agar, 20 g calcium carbonate and 1000 mL distilled water) were extracted with chloroform and purified by column chromatography, we obtained a new colourless bacterial metabolite which according to spectroscopic data proved to be serratin.
